Customer Testimonial

I wanted to write and give thanks for Ricky's efforts. He looked up options while I was busy at work and gave good advice and was knowledgeable when I wasn't.

Great amp with little power draw. Have this running a bazooka 10" tube and 4-6.5 marine boss speakers and can play for hours on my two batteries and not have to worry about starting my yammy 250.

I installed the amp on a polaris rzr, pushing a 10" sup and 2 6" mids, it sounds great and the best part is when it gets muddy i just spray it of. I'm not a stereo man but due to the sound and especialy the durability i would highly reccomend.
